Over the past 6 months my poker targeted parked domains have earned $1.86 per unique visitor.
I’m sure I could earn more than this if I pointed the traffic at a good quality poker portal but that would mean I would have to work :laugh
It would also take some time to get a player base large enough to match the PPC income, some limited testing I’ve done would suggest 6-12 months before my income was back up to what it is now.
I think I could double or triple my income within about a year if I did this (I’d also benefit from additional SE traffic, word of mouth, and the fact I could push the traffic back to PPC once the portal is established) but getting over the serious drop in income in the first month or two is one hell of a barrier to face and I can’t do it at the moment ’cause I’m buying a house.
